SEEDLING PLANTING DEVICE

To provide a seedling planting device that can obtain a planting trajectory for performing proper planting by high-speed planting in order to solve such a problem that a seedling planting device in which a counter gear and a planetary gear that are engaged with a sun gear consisting of a non-circular gear rotate around the sun gear with rotation of a rotary case, and a seedling planting tool is attached to the planetary gear conventionally exists, however, it is difficult to obtain a planting trajectory for performing proper planting by high-speed planting in a mechanism of the sun gear, the counter gear and the planetary gear in the rotary case.SOLUTION: There is provided a seedling planting device in which base parts of rotating cases 42, 42 are provided on both ends of a rotary case 41 that rotates with drive of a seedling planting device drive shaft 40 provided in a planting transmission case 16, seedling transplanting tools 43, 43 respectively having planting claws 1a are provided on the tip parts of the rotating cases 42, 42, non-constant velocity transmission mechanisms are provided in the rotary case 41 and each of rotating cases 42, 42, the tip of each planting claw 1a operates in a desired planting trajectory.SELECTED DRAWING: Figure 9 【課題】従来、回転ケ－スの回転により非円形ギヤよりなる太陽ギヤに噛み合うカウンタギヤと遊星ギヤが太陽ギヤの回りを回転し、遊星ギヤに苗植付具を装着した苗植付装置がある。然しながら、回転ケ－ス内の太陽ギヤ、カウンタギヤ及び遊星ギヤの機構では、高速植付けで適正な植付けを行なう植付け軌跡を得ることが困難であった。そこで、高速植付けで適正な植付けを行なう植付け軌跡を得ることができる苗植付装置を提供する。【解決手段】植付伝動ケース１６に設けた苗植付装置駆動軸４０の駆動により回転する回転ケ－ス４１の両端部に各々回動ケース４２，４２の基部を設け、該回動ケース４２，４２の先端部に各々植付爪１ａを備えた苗植付具４３，４３を設けると共に、回転ケ－ス４１及び各回動ケース４２，４２内に不等速伝動機構を設けて、各植付爪１ａ先端が所望の植付け軌跡にて作動する苗植付装置。【選択図】図９
